This study examines the social networks among Niẓāmiyyah Schools built by the great vizier Niẓām al-Mulk in the early period of the Seljuk dynasty. Niẓāmiyyah institutions served as higher educational centres for religious studies in the middle ages and contributed significantly to the development of the madrasah administration system. There were strong social networks among individuals and organisations associated with the Madrasah Niẓāmiyyah. The administrative system succeeded in creating a strong relationship between professors and students of one madrasah to another. Academic activities included debating among professors, visiting-professors, research activities and employment of graduate students in its administration system.
